Designed by John Browning, the Model 90 was the first pump action .22 rifle ever successfully developed and manufactured, following in the footsteps of the Spencer shotgun and Colt Lightning. The Model 1890 will only fire the round specific to that gun, meaning a Model 1890 stamped ".22 Short" on the barrel will not fire .22 Long, .22 Long Rifle, or .22 WRF despite there being other 1890's chambered in those calibers. Despite this unusual features, the Model 90 is prized by gun collectors due to its reputation for being well made and durable. This rifle features a 24-inch octagonal barrel. Its wood and bore are in fair condition. Its metal is in good condition.
